To all considering a PetCool . . . We tried it out over the Labor Day holiday and it is all you would expect in a teardrop A/C. It kept us cool as a breeze off Lake Louise. BTW, does anyone know where Lake Louise is? Anyway, we got ours direct from the factory, as a "scratch and dent," and while it did have a slight cosmetic flaw, the operation was exceptional. As you can see below, we routed it through the window as a temporary fix. We anticipate putting in permanent ductings, much as Sonetpro did, so that we can keep the unit separate and connect it behind "Schmoopie" while camping. The unit is not heavy (42 pounds +/-) and is surprisingly quiet. It also has a "fan only" function, for temperate climes and conditions where only moving air is necessary.

It has heating, cooling and "fan only." It comes with two ducts (shown above) as well as two adapters which I screwed to the plywood insert in the door, replacing the screen in our Yoder Toter 5X8. A drill bit is supplied to drill holes of an appropriate size.

It does lend itself to both interior (permanent) and exterior (temporary) installation. We opted for the second option, and will install ducting from below the galley hatch up through the galley, then a 90 degree turn into the cabin. It has both supply and return lines. Sonetpro installed this unit inside his FishInn - sans cove - and has pictures in his album.

Ideally, for this type installation, you would be better served to have the unit on hand when building, so that you might customize your tear to accomodate its exact size. See also Sonetpro's venting solution, using a boat vent. Slick!

The timing of this post is great, our Pet Cool just arrived today! We got ours used on ebay, it's the 2000 BTU model with heat. It seems pretty quiet, and looks like it will be perfect for a tear.

We had bought one on ebay earlier this spring, but the seller backed out of the sale 3 weeks after they had our money, claiming that it didn't work. We think she was just unhappy with the selling price ($199). After not getting that one, we were thinking about modifying a 5000 BTU window unit we have, but it's so darn loud that we decided to look for another Pet cool.

I'm thinking about putting my intake and return air ducts on opposite sides of the trailer, hopefully to increase circulation. Any one using one have any suggestions for duct placement? We were also wondering how the thermostat works, since it won't be in the area that is cooled.

It does heat but not a lot. Its only a 300W heater so it only puts out tepid air, especially if you're running it through a long hose outside like I was. Enough to take the chill off but not enough to make the trailer balmy or anything.
